Teensy 3.6/4.1 USB Support for CCID USB Card Readers

shmorgan · Jun 14, 2022

I have a project where we need to connect a CCID USB Card reader to our Teensy 4.1 Based board. We would like to be able to just do the basic functions of detecting when a Card/FOB is scanned and receiving the Card ID. We don't need support right now for Writing cards or reading the extra data from the card storage.

I did some simple testing with the USB library and at least have it detecting the reader and displaying the correct description of the device.

The CCID standard is quite different than any of the other protocols, so I would looking for ideas on how to get started.

I have copies of the CCID Standard Docs and have been reading quite a bit, from what I see there needs to be 4 Pipes created to the device for proper communication. I think if someone can help me get started, I can get this going to share with everyone.

From what I gather, I would need the following Functions to communicate with the Reader.

Interrupt - IN
Bulk-Out
Bulk-In

On page 59 of the CCID Standard Document, there is an example of a basic Card Detected, Card Read, Card Removed example of the handshake.

The reader is from AB Circle and is the model number CIR315A

Here is the link to the CCID Version 1.1 Document:

https://www.usb.org/document-library/smart-card-ccid-version-11

Also, there is a project for a Linux Driver out there with support for this and many other Readers:

Sorry, I am not sure how much time and energy I be able to help. But will try to answer questions as they come along.

It should be doable, but it may take a bit of work to do. If this device was one that was based on HID, it is often a lot easier, as you can hopefully just hook it in with the hid parser code and your code is called with the different data fields... Sometimes there is still some work to do as many of these devices still expect some handshake to get started. Like the equivalent of some IOCTL that says something like: Start sending report 1...

For devices that implement their own interface this can be a lot more work. As you mentioned, you can look at the Linux driver and for sure get hints. Often times they end up with lots more setup than is needed.... Other times I look for others who have implemented it, like USB Host Shield 2... But I don't see anything.

So then some times, I try to capture the USB data that goes between it and either a windows or Linux Host and then try to deduce which parts I need.
If you have a fancy scope like Paul has Beagle... it is easier.

I don't. If the device communicates with USB2 and not at high speed (480mbs), then I can capture some of this with my Saleae Logic Analyzer. But it is a pain.
I used to capture everything with their previous software, and save to file, then have to do several steps to reduce the sometime millions of lines out output, down to something like maybe 100 lines that are of interest. I have now have a hacked up version of their USB protocol analyzer plus an HLA which does a lot more of the data reduction for me, but it is still a pain...

From there, I then start sort of hacking my way along...
I plug it in to the host and capture how much data I get so far and compare to the other code and then generate the next message and see happens...

I also try to gather as much data as I can from something like linux. For example I plug it in to my Ubuntu x86... machine and then
print out system information like: dmesg | tail -40
To see what things it tells me...

I then use lsusb to give me more information.
like from lsusb -v
I always have to look up the command format, to specify the device...)
And it will typically tell you about things like endpoints and the like.

Again I know this is not much help

Thanks for the reply!! I have made some progress.

First, the device in question is NOT an HID device, it is strictly a USB CCID device.

I ended up taking the Serial.cpp section, duplicated it to CCID.cpp and have modified it quite a bit. I now have it getting the Device/Interface/Endpoint Descriptors!! So far I have only modified the claim function. See Sample output with Debugging enabled.

So I believe if I can 'attach' to the Interrupt-IN pipe, not sure how, but I would receive NotifySlotChange Messages, which is really all I'm looking for right now.

My question is how do you attach to the Interrupt-IN pipe and read back the data? Do I assign Pipes to all three endpoints, or are Interrupt Pipes treated differently?

I also have one of the Saleae Logic Analyzers, but never used it for USB, mostly for SPI/I2C and Pixel Data.

Based on the Doc on page 59 it flows like this

USB HOST CHIP CARD READER

Card Inserted on Slot #0

<-------- Interrupt - IN
RDR_to_PC_NotifySlotChange Message

Bulk-OUT ------------>
PC_to_RDR_IccPowerOn

<-------- Bulk - IN

(Return Card State and Power State)

Bulk-OUT ------------>
PC_to_RDR_XfrBlock

<-------- Bulk - IN
RDR_to_PC_DataBlock
(Return Card State and Power State)
and Card Data

Card Removed from Slot #0
<-------- Interrupt - IN
RDR_to_PC_NotifySlotChange Message

Some of the data has been removed as it was un-necessary.

I think I'm stuck at this point. The Device Identification is working, but I can't seem to get any other interaction going with the reader.

I believe I am sending request to the device, but not seeing any responses so far, Also when a card is scanned, it should create an Interrupt Message, and I don't seem to be able to detect that.

Could really use a little help getting this going.

Saleae - Which one do you have... (I have a few), but do most of my USB stuff with PRO 8...
It was a real pain to get the data down to something useful. But I now have hacked up version of USB low level analyzer which outputs new format output, and a High Level Analyzer which can strip that down to something useful. Was at one point trying to get Saleae to integrate it into main USB...

But not yet: Some details are up at:

When a device is plugged in. Normally the raw stuff in same cases out of the released USB analyzer the save to file, may output 200k lines of data, which I often can reduce to probably about 50 lines that are interesting.

I have also had some luck using WireShark app and PC or Linux to capture some of the stuff. But it usually takes me awhile to remember how I do it the previous time. And then filter it down to where you may get similar type data...

Or use a actual scope, like: https://www.totalphase.com/products/beagle-usb480/
Which I think is what Paul uses... For me, who just does it for the fun of it... I have not invested in one of these...

Most of the devices have a handshake where they go through and where we will ask the device something and wait for them to respond, and depending on the response will ask for the next thing

I will try to take a look at their document/device driver. But is is again easier to look st what they do when plugged in to help to direct where to look next.

Kurt,

The Saleae I have is the older Black Logic 8, So I'm not sure it can capture USB at that speed.

If you want to helpout on this, I can send you the code I have so far and mail you one of the Circle Readers with a few test cards for testing. PM me and I'll send you my contact Info.

I have done the WireShark Trace and could provide an example capture file with the Filter needed to view the USB traffic.

Here is my latest Trace:

At the bottom, you will see I am trying to send out a Request for Slot Status to the Endpoint 1 - Bulk-Out Pipe. But not sure how to get the response back from device.

Kurt,

Turns out that my Saleae is more usefully than I thought!! It seems to capture the USB data with no major issue. It would be great if we could do a quick zoom and see if I'm on the right track.

I'm running version 2.3.5 of the Logic 2 software and it seems to decode the data pretty well!! I wish they had filtering!!!!

Well, I'm jumping down the USB Trace rabbit hole and see where it leads!!

Thanks so far for your help and suggestions.

-Steve

Note: I have attached a Capture from the Card Reader.

KurtE · Jun 18, 2022

I should have mentioned, with data from the USB LS FS Analyzer. I typically need to then switch the capture type to Packets instead of control transfers.

I then look for those packets that have "Data" and in this file of > 52K lines there are only 2 with Data...
What version of the Logic Analyzer software are you using? I am currently using the Version 2 stuff with their latest release 2.3.55

So the interesting thing would be if you have a setup, like connected to PC/Linux/??? that recognizes the board and maybe one or two card detection and can capture that in Packet mode.
Then output the file as mentioned, which could be very big!

Then if possible try to reduce the data to something manageable, I showed some of steps I did in a few places like the posting:
https://discuss.saleae.com/t/any-videos-or-tutorials-on-usb-ls-fs-analyzer/643

What I have found is that I use the Linux grep on the file and find all lines that have data and return it plus the line before it...
something like: grep -i -B 1 data.csv > extracted_data.csv

and then I use editor to remove -- lines
And then I combine the two lines into one...

And that hopefully gives a reasonable number of lines to look through.

Forgot to mention in previous post,

Also hard to fully know what is going on, without seeing some of your startup code.

For example: With your endpoints,

For those which are to receive data from the device, have you queued up transfer objects with buffers, that are setup to receive the data.

Like if you look in lets say keyboard.cpp you will see code that looks like:

Code:

	datapipe = new_Pipe(dev, 3, endpoint, 1, 8, interval);
	datapipe->callback_function = callback;
	queue_Data_Transfer(datapipe, report, 8, this);

Where we then have:

Code:

void KeyboardController::callback(const Transfer_t *transfer)
{
	//println("KeyboardController Callback (static)");
	if (transfer->driver) {
		((KeyboardController *)(transfer->driver))->new_data(transfer);
	}
}

Which is defined as a static function. Which then grabs our object pointer out of it and calls new_data

Code:

void KeyboardController::new_data(const Transfer_t *transfer)
{
	println("KeyboardController Callback (member)");
	print("  KB Data: ");
	print_hexbytes(transfer->buffer, 8);
...
	queue_Data_Transfer(datapipe, report, 8, this);
}

Which then processes the data and then queues back up the a transfer structure to receive the next one. Note in this case we are only setup with one receive buffer/transfer, with other classes we may queue up multiple transfers, to handle faster devices which may queue up multiple things before we have chance to process.

My guess is there is still some setup needed, like maybe to ask which report format or start device or ... This is needed Maybe multiple

Ok, so this morning, I captured and filtered traffic with the card reader connected to both the Windows Machine and the Teensy. On each one, I scanned 5 cards.

I have included the traces here. Hope the filtering helps!!! The filtered files are the ones with _out in the file name.

The one thing I see right off, is in the Teensy Trace, a bunch of DATAT0 with all the bytes set to 0x00, from Time 2.89 until the end.

Actually your capture files work nicely...

I then simply added my version of the USB LS/FS LLA and then my HLA, that uses it...

From that I could get data like:

And the report view output, has data from my HLA, like:

IN , DATA1 , 0x5 , 0x1a ,  0x50 0x2

So I sort of skipped ahead... Did not look for any special things yet set the SETUP... Many of those looked like read in descriptors of one form or another.
And I show one of the first Output messages...

Again I could be wrong, but looks like it is sending: OUT , DATA0 , 0x1 , 0x1a , 0x65 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0
So if you look at the 0x65, and in the datasheet table 6.1 is PC_to_RDR_GetSlotStatus
Which those 10 bytes are probably that message: P29

Next line is an input: IN , DATA0 , 0x2 , 0x1a , 0x81 0x0 0x0 0x0 0x0 0x0 0x0 0x2 0x81 0x0
So 0x81 at table 6.2-1 p48 RDR_to_PC_SlotStatus
The format of the message is on p50
so bStatus = 0x2 Not sure is this the Time Extension is requested???
bError - 0x81

But my strategy would be to walk though each of these OUT/IN pairs and setup sort of a state table or the like, and try to emulate what the windows driver was doing... For example I see a few outputs starting with cammand 0x61 Set parameters, which might be interesting.
Likewise 0x62 Power On...

Hope that helps

I believe you are right on track with that. I did get the interrupt receive working and can now detect when a card is in range and when it is removed!! So that is part 1 of my requirement. Woo Hoo!!!

I just added a routine to send out the NotifySlotChange message and I am getting a response, but no idea what it means, as the document is kinda unclear on this. Need to dig in and see if I can figure out what it means.

Right now, I am not following the Bulk-Out Format as I am not changing the bSeq code yet, Going to test that now, create a global to hold that value so all outbound messages will have a changing value.

I know to read a card, the sequence of events described is to receive the Interrupt message of card change, then you send power off, power on, get slot status and then read the card data.

I think we are very close to having the starting of support for CCID devices.

Here is a Debug Trace so far:

Seems I am getting a good DataBlock Message with bStatus = 00 and bError set to 0x81.

Per page 55, is bmCommandStatus field is 0, the command processed without Error. Look like
bError may be RFU (Reserved for Future Use?) when bStatus is 00.

It's Exciting to get this far!!

I think I have determined that the data in the abData section is defined as ATR (Answer to Reset), returned directly by the Card being read.

I have several example of cards, Fobs and even Disney Magic Bands that I can read with this reader.

Each seem to have a different Structure.

The 2nd byte is the size of the abData Structure
The 7th byte is the bSeq Number

My guess is that it somehow defines the card type and how much memory is on the card. I can't seem to find much info on the ATR structure.

KurtE · Jun 19, 2022

Looks like you are making progress...

As for the actual data not much I can tell you other than the data structure as I am sure you know on P49...
80 14 00 00 00 00 14 00 81 00 $$ 3B 8F 80 01 80 4F 0C A0 00 00 03 06 03 00 01 00 00 00 00 6A
MT = 80
App data length = 0x14 or 20 bytes
Slot = 0
Seq = 0x14
status = 0
error = 0x81 (User defined)
chain = 0
App data: 3B 8F 80 01 80 4F 0C A0 00 00 03 06 03 00 01 00 00 00 00 6A

As for what all of this data is??? Not sure...
For some of the cheap cards, like: Cheap white cards from Amazon, something like:
https://smile.amazon.com/Proximity-Printable-Compatable-readers-majority/dp/B06WLL29HM

It sounds like maybe you can find data in places like:

https://www.google.com/url?sa=t&rct...ts-wp-en.pdf&usg=AOvVaw3JMYtg_HC86nidxN-p3OJ8

You might also get some information from the linux driver you linked to earlier to see if you can find out how it processes each card...

shmorgan · Jun 19, 2022

Actually, more like these cards.

https://www.amazon.com/HiLetgo-Comm...ics&sprefix=nfc+reader,electronics,83&sr=1-10

I believe the ones you linked to are actual Prox Cards, this reader is a NFC reader. Different frequencies.

Yea, I got the first part of the structure just fine, it was the App data part I am lacking as it depends on the card manf.

I will contact Goto Tags on Tuesday and see if they can help out a bit. They will be our supplier for the Readers and Cards. Around 60 Readers and around 10K cards.

Going to be really cool.

I have it reading the number off the cards, and am still guessing at some of the Card Structures, as they are different between cards.

The one issue I'm seeing, if there is more going on on the Teensy 4.1. Other timers, network, web server, UDP, etc, I stop getting responses to request for data from the card. I still get the interrupt messages.

One thing I have noticed that is different between the Teensy USB and Windows Driver USB is the Huge about of traffic on the UBS Interface on the Teensy.

I have narrowed it down to one command and not sure what is causing the issue, may a retry loop of some kind?

Here is the claim section to setup the six data pipes.

If I un-comment out this line, the traffic on the USB bus is like 100X as much with a bunch of

SYNC,PID IN, Address=0x01 Endpoint=0x02 CRC OK, EOP
SYNC, PID NAK, EOP

Code:

queue_Data_Transfer(rxpipe2, rx1_2, rx_size2, this);

Code:

	//=====================================================
	// Setup Interface 1 Pipes:
	// Interrupt
	// Bulk-In
	// Bulk-Out
	//=====================================================
	
	rxpipe1 = new_Pipe(dev, 2, rx_ep1 & 15, 1, rx_size1);
	if (!rxpipe1) {
		 return false;
	}
	rxpipe1->callback_function = rx_callback1;
	queue_Data_Transfer(rxpipe1, rx1_1, rx_size1, this); // <<-- This Causing a huge amout of Traffic on the USB Port

	txpipe1 = new_Pipe(dev, 2, tx_ep1, 0, tx_size1);
	if (!txpipe1) {
		 return false;
	}
	txpipe1->callback_function = tx_callback1;
	
	// Setup the Interrupt Pipe to handle the two Interrupt Messages
	intrpipe1 = new_Pipe(dev, 3, intr_ep1, 1, 8, 0x0A);

		 return false;
	}

Been a while on this thread, but thought I'd give it a shot... I have a similar application where I'd like to host a USB NFC card reader via a Teensy 4.1 host port. Were you able to get this going, and is there any code released? Thank you!

shmorgan · Feb 13, 2024

It has been awhile and KurtE was very helpful. I had to put this on the back burner until our season was over, and am now looking at this again. I was able to detect reading a Card, and trigger a relay. Our first version required nothing more than detecting a card swipe and triggering a relay. This year, the requirements have expanded to reading the actual card number and possibly reading/writing the data section of the card. I hope to refresh my brain and get this going again. I have upgraded to the Saleae Pro 8, works much better and is a bit faster than the older one.

Kurt, I see that Saleae has done some improvements on the USB HS/LS decoder, does your decoder still work with the newer version?

What NFC reader are you planning on using? The one that I have played with so far is from GoToTags, it seems to work pretty well.

I was hoping to use the ACR122U NFC Reader Writer. For the short term I'm using a PN532/CH340 combination via USBSerial host, which works OK for low level communications. That might be fine for my app, but it's not available as a nice off-the shelf solution w/ enclosure.

As far as I can tell, the only real changes they made to their version is to add unicode support...

My fork of it with LLA support does not have that, but works fine for me so far with my HLA, which works for me to filter the data down to what I typically look at.
